title	CDT: A Computer-Assisted Diagramming Tool
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 91-109
summary	This paper describes the development of a computer- based diagramming tool (CDT) that supports incremental structuring of problem information using diagrammatic representations. Diagrams as graphic representations of symbolic propositions allow tentative reasoning and inferencing. The development of CDT has been carried out based on two observations. First, many diagrams are used to represent objects and relations between them. Second, diagrams comprise graphic Symbols arranged on a plane using topological and geometric relations to denote problem relevant information. CDT responds to these needs by incorporating a number of computational ideas: graphic interface, direct manipulation, constraint representation by demonstration, and specification and satisfaction of diagram composition rules.

title	A Computer-Assisted Diagramming System
source	Swiss Federal Institute of Technology, ETH Zurich
summary	This research investigates characteristics and generation of graphic diagrams used in support of analysis, presentation and synthesis of information in various domains. The research is aimed at the development of a software system which can be used to specify, generate and manipulate diagrams similar to the way they are represented and operated upon in traditional media.Diagrams are graphic representations of symbolic propositions that allow tentative reasoning and inferencing, and enable a person to focus on selected aspects of a situation that are deemed of interest. The economy and directness of expression found in diagrams seem to be the prime reasons why they are so ubiquitous in many domains. Despite these advantages, studies into supporting diagrammatic representations using computers are rather sparse. This research is an attempt at developing a comprehensive framework of thought in this direction.In the context of design disciplines like architecture, this research forms a part of the continuum of studies in computer aided design techniques and tools. While a large number of tools and techniques in CAD have emerged so far, usage of such tools, due to their underlying representations, expects and demands commitment of too many details too early in the design process. This research is aimed at characterizing and developing a computer based diagramming system to support tentative reasoning using diagrams, and thus hopes to extend the scope of CAD environments in design.The thesis first articulates motivations for this topic in detail. Next, a discussion on the role played by diagrams as conceptual tools in various domains is presented. It is followed by a detailed look at characteristics and components of diagrams viewed as a graphic communication system. Next, a comprehensive set of requirements for an ideal software environment for diagramming tasks is developed. A prototype system called CDT was implemented and is used to demonstrate ideas developed in this research. The study concludes with some observations on contributions of this research effort and possible future extensions.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	The Vector-drawing as a Means to Unravel Architectural Communication in the Past
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q9a
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

summary	The colour video recording Urban Simulator in TUT was built very early compared with the development of video systems. A contract for planning the simulator electronics, mechanics and camera systems was made in january 1978 with two TUT students: Jani Granholm (computer science and engineering) and Ilkka Alavalkama (machine design and automation). Ease of control and maintenance were asked by side of ”human movement inside coloured small-scale architectural models”. From the beginning, all components of the system were carefully tested and chosen from various alternatives. Financial resources were quite limited, which lead to a long building process and to self-planned and produced mechanical and electronical elements. Some optical systems were constructed by using elements from various manufacturers.

title	The Changing Image of the City
source	University of Utrecht
summary	The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the often subtle changes in the townscape. Though in many cases we have a general knowledge of the choices made in urban management, the most difficult problem is to detect the underlying decisions. This raises the question to what extent these changes and also the continuities are the result of deliberate choices in urban management and to what extent they are autonomous developments in the townscape resistant to interventions. Using different kinds of visual information as a basis, computer visualization techniques are used in the present study to examine some cartographic maps and to reconstruct the urban development in the twentieth century of the town of Heusden three-dimensionally in significant phases. The resulting visualization provides us with a tool for a better understanding of the dynamics of urban transformation processes, typologies and morphological changes and continuities.

title	Knowledge-based Stair Design
doi	https://doi.org/10.52842/conf.acadia.1993.163

summary	The application of computer--based technique to support architectural design has often concentrated on matters of representation. Typically, this means computer-aided drafting, and less frequently, computer-aided modeling and visualization. The promise of new computer-based tools to support the process of design has thus far failed to produce any significant tool that has had a widespread impact on the architectural profession. Most developments remain in university based research labs where they are used as teaching instruments in CAD courses or less often in design studios. While there are many reasons for this lack of dissemination, including a reluctance on the part of the architectural profession itself, the primary obstacles deal with difficulties in explicating design knowledge, representing this knowledge in a manner that can be used for design, and providing an intuitive and effective user interface, allowing the designer to easily use the tool for its intended purpose. This study describes a system that has been developed to address a number of these issues. Based on research findings from the field of Artificial Intelligence which expounds on the need for multiple techniques to represent any complex area of knowledge, we have selected a particular approach that focuses on multiple techniques for design representation. We review this approach in depth by considering its many facets necessary when implementing a knowledge-based system. We then partially test the viability of this approach through a small case study, implementing a knowledge-based system for designing stairs. While this effort only deals with a small part of the total design process, it does explore a number of significant issues facing the development of computer-based design assistants, and suggests several techniques for addressing these concerns.

summary	Color courses are traditionally based on exercises carried out with either water color or colored paper. Use of the computer as a tool for teaching color theory and analyzing color in architecture was the topic of a course given at the School of Architecture and Planning at the State University of New York at Buffalo, USA where I was an exchange faculty in the academic year 1993/94. The course was structured into 3 topics: color theory, color perception and application of color.

summary	Beginning in 1993, small groups of students of architectural design at different institutions around the world participated in collaborative design projects using a variety of tools, including CAD, Internet and teleconferencing. This programme, known as the "Virtual Design Studio" (VDS), allows students to work collectively with colleagues from different cultures and climates who are thousands of kilometres and in different time zones. Most recently, in February 1994, four institutions in N. America, one in Europe, and one in S E Asia participated in VDS’94. This paper explains the operation of the VDS and explores the future of the VDS as a potential tool for architectural design education. In particular, we review what we have learned in employing computer tools to extend the teaching in design studios into a "virtual" experience.

title	The Evolution of an Interface for Choreographers Evolving Design
source	Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems 1993 pp. 115-122
summary	This paper describes the evolution of the interface to Life Forms, a compositional tool for the creation of dance choreography, and highlights some of the important lessons we have learned during a six year design and implementation period. The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected as necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version. The choreography and composition of a dance is a complex synthesis task which has much in common with design. Thus, the lessons learned here are applicable to the development of interfaces to such applications as computer aided design.

title	A Proposal of Iconic Map on Computer Aided Architectural Design: 3DIMCAAD
doi	https://doi.org/10.52842/conf.ecaade.1993.x.g9p
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	During the development of my graduation thesis I had to propose a subdivision of informatics technologies for architectural design into several research fields, each of them characterized by specific aims. This kind of subdivision was originally configured as an orientation tool inside the wide CAAD discipline, and only in a second time it took the features of a complete organization layout in which it is understandable not only the position of each single discipline in comparison with the others but, above all, the connections and interactions between them. The model, obtained as the result of many handlings but undefined yet, has been named 3DIMCaad (3 Dimensional Iconic Map on Computer Aided Architectural Design) and, in according to an initial hypothesis it could be regarded as a map of the sectors pointed out by my proposal, in fact, it is a iconic model of the connections and differences between the informatic main topics that I analysed. Every main topic is represented by a spheric nucleus linked to the others by a connection line (the ''pipe''), the dimension of which, quite generous, makes the observer understand the numerous interactions and exchange presents if two main topics are linked.

title	Exploring Structural Morphology Using CAD
doi	https://doi.org/10.52842/conf.ecaade.1993.x.d1k
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Often in the design process the student's imagination is restricted by their inability to visualise, model or accurately sketch ideas for innovative structural systems. By using CAD as a design tool it is possible to explore the morphology of complex structures and to be able to produce perspective drawings of them with relative ease. Within AutoCAD there is a small library of standard three-dimensional objects and surfaces that can be called upon to generate more complex forms. However, to further facilitate the architectural design process, an extended library of innovative structural forms would allow the professional designer, or student, greater design freedom and any increase in the palette of structural forms available should stimulate creativity. As practical examples, the paper describes how students have been encouraged to experiment with the use of structures which can only be physically modelled with difficulty and which are also difficult to represent on the two- dimensional surface of the drawing board unless the geometry has previously been determined by the methods described. These are (i) Reciprocal Frame three-dimensional beam grillage structures and (ii) plate domes created from lattice structures by point-to- plane duality. The problem, of representation of these structures has been overcome, in the first case, by generating AutoLISP procedures to draw the complex three-dimensional geometrical form automatically in AutoCAD and, in the second case, by the development of the computer program CADual.

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

summary	Abstract as well as functionally dependant design exercises are essential components of an architectural education at nearly every university. Their goal is to provide architect students with a feeling for proportions, colours, materials etc., and to teach and train them in threedimensional thinking. Pictures and concepts, developed by the designer are materialized by various technologies such as with pencil and paper in the traditional two-dimensional techniques or with clay, wood, paper etc. in three-dimensional modeling. Now the computer and the CAD-system join the palette of the designers available resources in presentation as both a two-dimensional and a three-dimensional medium. Although CAD is often considered and taught to be only a better drafting tool, the educational goal of our group at the University of Dortmund is to employ CAD as a design support medium. The prerequisites for work with the computer and the CAD system are provided in a compulsory two semester undergraduate subject. Basic programming, work with spreadsheets etc. are some exemplary themes provided in the form of lectures and practical exercises. A main emphasis of this instruction is the mastery of three-dimensional working technology with a comprehensive CAD-System. In cooperation of our computer science group and architecture chairs, seminars involving the use of CAD as a three-dimensional design tool, are offered as graduate courses. The seminars consist of loops of modeling and evaluating objects in a three-dimensional space. With this, the most possible realistic studies in colour, light and proportion take place exclusively on the computer.

summary	The Video and Multimedia studio at VTT, Technical Research Centre of Finland, started with endoscopy photography of scale models. Video recordings has been made since 1985 and computer graphic since 1989. New visualization methods and techniques has been taken into use as a part of research projects, but mainly we have been working with clients commissions only. Theoretical background for the visualizations is strong. Research professor Hilkka Lehtonen has published several papers concerning the theory of visualization in urban planning. This studio is the only professional level video unit at Technical Research Centre, which is a large polytechnic research unit. We produce video tapes for many other research units. All kind of integrated methods of visualization are useful in these video productions, too.

title	Looking into Endoscopy - The Limitations of Evaluation in Architectural Design

summary	The means available to architects in their age-old task of creating (most usually, though not necessarily) buildings that do not yet exist (ie. virtual realities), can be seen as falling into two groups. Those that help us develop architectural ideas (exploring), and those that help us evaluate or test them (illustrating). In the former category, we have, for instance, the ”drawing on the back of the envelope”, the discursive brainstorm, and the design ”conversation with ourselves via paper and pencil” (the drawing strikes back). In the latter, we may include physical model building, careful (projective) drawing (including drawings that are instructions for making), mathematical and design science modelling and calculating, visualising techniques such as the rendered perspective, most CAD (computer aided design) work and architectural endoscopy. These techniques may be thought of in two ways, as Bosselman reported: the explanation (eg. the organisational plan) and the experience (eg the ”photo-realistic” perspective). Attached to these we have rules for success, such as those of ”style” (in the broad sense of the personal style that allows us to assume that we have answers to problems that have yet to appear). It should be clear even from the list above that there are many more techniques and technologies for evaluation (illustration) than for exploration (design): such is the mystery of design. It is the primary purpose of this paper to invite those involved in providing the enormous effort that has gone into making such techniques for illustration — evaluation — to consider how their efforts help with that other, and crucial, area — that of exploring: and to redress some of the balance of that effort towards exploration. For it occurs to me (as a teacher of architecture), that evaluation does not provide a course for action — it merely helps us determine what may be wrong (according to some criteria with which we choose not to argue). And, no matter how right or wrong a design may be, knowing that it is wrong doesn’t help us either modify it, or find a better initial idea. It only tells us we are not right — always assuming the evaluative model is correct; perhaps.

title	Spatial Perception in Virtual Environments: Evaluating an Architectural Application
source	IEEE Virtual Reality Annual International Symposium, 1993, Seattle
summary	Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments.

summary	The interdisciplinary research project aims at the development of a hard- and software environment to support the representation, analysis, manipulation and design of urban development areas for architects and city planners. It was started in 1990 and involves three groups at the ETH Zurich: Architecture/Urban design - Processing of Geographic Data/Photogrammetry -Computer Sciences/CAAD. The first part of this paper will give an introduction to the goals and implications of the project by comparing it with a similar project one of the authors took part in as a student. Then the paper gives a brief description of the work of the three groups involved, an overview of the methods they employed and the results that were achieved. The main focus will be on the work of the CAAD group . Finally some conclusions are drawn and problems are discussed. The future work includes the testing of the tool by students during the winter term 1993/94.

title	A Tool for Conceptual Design Evaluation Based on Compliance with Site-Development Briefs and Related Planning Regulations
doi	https://doi.org/10.52842/conf.ecaade.1993.x.c6i
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.
